I NEED HELP AS FAST AS YOU CAN :You launch a weather balloon. It travels high into the atmosphere. Below is the beginning of three models drawn by another student to explain what is happening as the balloon rises higher in the atmosphere. Write a short explanation for what is happening to the pressure inside and outside of the balloon as it rises. Be sure to include each altitude (Near Earth, Midline, Near Space). *

Velocity is a description of both speed and direction, therefore it - a vector - a force arrow - the same as acceleration - a magnitude

Which of these is not a possible type of energy transformation? a. electrical energy into light energy b. sound energy into nuclear energy c. potential energy into kinetic energy d. kinetic energy into mechanical energy

Along wire of diameter 1 mm is submerged in an oil bath of temperature ∞ 31°c. the wire has an electrical resistance per unit length of 0.01 ω/m. if a current of 103 a flows through the wire and the convection coefficient is 500 w/m2·k, what is the steady-state temperature of the wire? from the time the current is applied, how long does it take for the wire to reach a temperature that is within 1°c of the steady-state value? the properties of the wire are 8000 kg/m3, 500 j/kg·k, and 20 w/m·k.
